Hi all,
Everybody at WineConf (myself included) seemed pretty happy about the idea to have Wine use Windows 7 mode by default. However, it looks like Steam does not accept the -no-cef-sandbox parameter in Windows Vista and later. This means that if we switch to Windows 7, most parts of Steam will crash.
I see a few options:
- Ask the Steam developers to make -no-cef-sandbox work in all
versions of Windows. 2. Tell users to switch to Windows XP mode before using Steam. 3. Commit some nasty hack to handle the syscall and continue normal processing.
This needs further discussion.
Hi Alex,
There are more issues than just the sandbox, though the sandbox is the most difficult to solve (IMO). My concern is that no matter what we get Valve to do that the Chromium sandbox is getting integrated into more and more software, so it seems like we have to find a solution that works for more than just Steam.
So, I have a bunch of code for getting the sandbox working in 32-bit mode without doing anything horrible, I'm happy to share updated versions if anyone is interested. The problem is getting the sandbox working in 64-bit mode, which also prevents it from working in WoW64 mode. There would also be some difficulty getting the 32-bit version to run on Windows 8+ due to the way that MS changed the assembly, but if we can solve the 64-bit problem then that solves this problem as well. So, if anyone has a good idea for trapping SYSENTER exclusively for ntdll then I'm all ears.
